CVE-2026-125372: REBUILD authorization bypass in FeedsListController

CVE-2026-125372 · Severity: medium · CVSS 4.3 · Published 2026-11-10

REBUILD is an open-source enterprise management system that includes a feeds feature for sharing content and comments. An authenticated attacker can bypass authorization checks in the feeds module to view private or team-scoped feed content, images, attachments, and comments by guessing sequential record IDs. This allows unauthorized information disclosure of sensitive business data.
